cds-question@unistra.frmultiple-starsThe results of speckle interferometric observations of 115 metal-poor stars ([m/H]<-1) within 250pc from the Sun and with proper motions mu>~0.2"/yr, made with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences, are reported. Close companions with separations ranging from 0.034" to 1" were observed for 12 objects - G76-21, G59-1, G63-46, G135-16, G168-42, G141-47, G142-44, G190-10, G28-43, G217-8, G130-7, and G89-14 - eight of them are astrometrically resolved for the first time. The newly resolved systems include one triple star - G190-10. If combined with spectroscopic and visual data, our results imply a single:binary:triple:quadruple star ratio of 147:64:9:1 for a sample of 221 primary components of halo and thick-disk stars.2008AstBu..63..278Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/AstBu/63.278CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/325/159 : Companions to M dwarfs within 5pc (Leinert+ 1997)J/A+A/385/87 : Speckle interferometry of nearby multiple stars (Balega+, 2002)J/A+A/422/627 : Nearby multiple stars speckle interferometry (Balega+, 2004)J/other/AstBu/62.235 : Metal-poor stars speckle interferometryhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/AstBu/63.278https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/AstBu/63.278http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/AstBu/63.278https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/AstBu/63.278https://vizier.iucaa.in/viz-bin/votable?-source=J/other/AstBu/63.278http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/AstBu/63.278GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/AstBu/63.278/table1 (Results of the speckle-interferometric measurements for resolved objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/63.278/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/63.278/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/63.278/table1?GETtext/xml+votable180.050000true40.30683369.77003030.005555555555555556Cone search capability for table J/other/AstBu/63.278/table2 (Speckle-interferometric measurements of objects resolved by Rastegaev et al.
